A company sells two sizes of microwave ovens: The small size and the large size. The demand functions for the microwave ovens are given by ps =150-0.5x-0.2y and P =250- 0.1x-0.5 y, where Ps and pi are the prices of the two sizes in dollars, x is the units of the small microwave ovens sold each week, and y is the units of the large microwave ovens sold each week.

Question
A company sells two sizes of microwave ovens: The small size and the large size. The demand functions for the microwave ovens are given by Ps =150-0.5x-0.2y and Pj =250- 0.1x-0.5 y, where ps and pi
are the prices of the two sizes in dollars, x is the units of the small microwave ovens sold each week, and y is the units of the large microwave ovens sold each week.
(a) Determine the total revenue function R(x, y) .
Answer:
(b) Rx(50, 30)=
This number means that, when
small microwave ovens and
large microwave ovens are sold per week, if the sales of the small microwave ovens
increase by 1 unit per week, and the sales of the large microwave ovens remain constant at
units per week, then the total revenue
--Select--- v by approximately $
per week.
(c) Ry(50, 30)=
This number means that, when
small microwave ovens and
large microwave ovens are sold per week, if the sales of the large microwave ovens
increase by 1 unit per week, and the sales of the small microwave ovens remain constant at
units per week, then the total revenue
--Select-- v by approximately $
per week.
